[LLVMdev] Issue with std::call_once in PPC64 platform
...Liu to the thread.
Jiangning reported a similar issue on the llvm-commits list on Debian aarch64.
In general it sounds like std::call_once may not really be bug free.
Jiangning, can you please provide your gcc/libstdc++ version?
Thanks,
-Chris

[LLVMdev] Issue with std::call_once in PPC64 platform
Ok, I'll put a patch together to fix this later today. I'll probably do
what Reid was suggesting and use what is already in there for Windows.
Thanks,

[LLVMdev] Overriding TargetRegisterInfo::hasReservedSpillSlot
...also. It makes it
impossible to call MF.getFrameInfo() without casting the constness away.
In such cases, is it best to cast away const, or remove the qualifier
from the parameter?)
Thanks for any help!

[LLVMdev] Getting command line options to affect subtarget features
...ction.
I'm sure there must be an obvious way to do this, but peeking at code
from other targets hasn't enlightened me. Any advice for how I can
accomplish this?
Thanks! I appreciate any help.

[LLVMdev] Issue with std::call_once in PPC64 platform
...builders/clang-ppc64-elf-linux2/builds/16444/steps/compile.llvm.stage2/logs/stdio
It is failing for me both in BE (gcc 4.8.2) and LE(4.9.1). I am compiling
with clang 3.5, but those are the gcc toolchains I am using.
What do you think is the best way to fix this?
Thanks!

[LLVMdev] powerpc XFAIL question
...rated for Clang and GCC is
identical.
Question: Does anyone know on what flavor of powerpc this is expected
to fail, and why? Or should I just remove powerpc from the XFAIL list
for this test?
Thanks,
Bill

[LLVMdev] FileCheck for instructions of indeterminate order?
...igure a way to test
this more safely.
All help appreciated!
Thanks,
Bill
N.B. I found the nondeterminacy at -O0 to be somewhat surprising...is
there some other option I need to avoid instruction reordering?

[LLVMdev] Issue with std::call_once in PPC64 platform
Hi all,
I observe that r220932 (Removing the static initializer in
ManagedStatic.cpp by using llvm_call_once to initialize the ManagedStatic
mutex.) is causing tablegen to segfault in PPC platforms during static
initialization. The crash happens while calling std::call_once introduced
by this patch in the wrapper used in getManagedStaticMutex.
I understand this call is buggy for some platforms

[LLVMdev] Types vs. register classes in instruction patterns -- effect on FastISel
Hello,
In http://llvm.org/viewvc/llvm-project?view=revision&revision=177889 and
http://llvm.org/viewvc/llvm-project?view=revision&revision=177890 (along
with some follow-up patches) the PowerPC back end was changed to use
types instead of register classes in instruction patterns. This matched
similar changes that Jakob made for Sparc in r177835.
I've recently come across an
